DOOR-SUPPORTING VISE.

SPECIFICATION forming part of Letters Patent No) 423,719, dated March 18, 1890.

* Application ned July s, 1889. senti No. 316,775. (No model.) l

To aZZ whom it may concern: Be it known that I, WILLIAM BArEsoN, builder, of the city of Toronto, in the county of York, in the Province of Ontario, Canada,

have invented a certain new and Improved Door-SupportingVise, of which the following is a specification.

The object of the invention is to design a simple instrument which may be easily carj projecting from the said clamp and having On either side of it an expanding jaw designed to form a vise to grasp and support the door inserted between them, the whole being constructed substantially as hereinafter more.

particularly explained.

Figure l is a perspective view showing my device in operation. Fig. 2 is an enlarged perspective view of the device.

In the drawings, A represents the bottom half of a clamp, and B the upper half, which upper half is pivoted at ct to the bottom half A. A centering-nger C projects, as indicated, from the bottom halfA of the clampA and has a blade formed on its end. On either side of this blade wings b, of equal length, project. Two arms D are pivoted on the clamp A, as shown, and the flaring jaws E, formed on the lends ot' the arms D, project 35 beyond the end of the centering-finger C. Between the inner ends of the arms D, I place a spring F, designed to hold the inner ends apart.l

G is a nut screwed on the end of a bolt pass- 4o ing through the clamps A B. Between these clamps and upon the said bolt I place a spiral 'sprin g H.

It will be noticed that my device is portable and mayV be easily fixed into position, as in- 45 dicated in Fig. l. In this case the clamps A B are screwed onto the table I, and the edge of the door J is pushed between the flaring jaws E, the sharpened centering-linger C entering the edge of the door, thus centering 5o it and holding it in posit-ion with the assistance of the jaws E, which are actuated by the spring F, as indicated.

What I claim as my invention is The clamp A B, provided with a suitable 55 bolt, nut, and spring, in combination with the pivoted arms D, actuated by the spring F, and having daring jaws E, projecting beyond the centering-fingerA C, which is fixed to the clamp, as shown, substantially as and for the 6o purpose specified. i
